High winds toppled trees in Henderson and downed power lines which blocked both north and southbound lanes of Interstate 15 for about 40 minutes just north of the Warm Springs overpass. Rainfall amounts of 0.75 to 1.20 inches fell in less than 30 minutes in many locations producing widespread street flooding
